Question

find the missing term that completes the square of a² + 4a

Answer 1

Answer:

4

Explanation:

Given the expression:

$a^2+4a$

To complete the square:

First, identify the coefficient of a.

• The coefficient of a = 4

Next, divide the coefficient by 2 and square it.

$\begin{gathered} \frac{4}{2}=2 \\ 2^2=4 \end{gathered}$

Thus, the missing term that completes the square of a² + 4a​ is 4.
